This was a couple years ago so I don't even remember
I have a Ruby/Rails application deployed on AWS ElasticBeanstalk and I use Sidekiq with Redis to handle all of the background jobs.
My app has events that users can create and there's a job that runs weekly that emails users, notifying them of the upcoming events. Lately I've beeg seeing this error:
ActiveJob::DeserializationError: Error while trying to deserialize arguments: Couldn't find Event with 'id'=45
This doesn't make sense to me because the event with this ID was created at least 3 days before the job ran. When I check the console or database, the event clearly exists and hasn't been updated or deleted. Why can't ActiveJob find it? Has anyone seen something like this before?
